tently into a sponge, cotton, or like absorbent or directly from thebottle, and has for its object to im rove the construction and increasethe e 'ciency and utility of devices of this character. l

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed. A

In the accompanying drawings, forming a part of this speclfication, andin which-corresponding parts are denoted by like designating characters,is illustrated the preferred form of embodiment of the invention capableof carrying thesame into practical operation, it being understood thatthe invention is not necessarily limited thereto, as various changes inthe shape, proportions, and general assemblage of the parts may beresorted to without departing from the fprinciple of the invention orsacrificing any o its advantages.

y'In the drawings thus employed, Figure 1 is a sectional elevation ofthe improved device. Fig. 2 is an enlarged'sectional detail of theplunger and its tubular stem. Fig. 3 is aperspective view of thecombined cylinder and supporting member detached. Fig. .L1 is atransverse section of the lunger-stem and with the packing-washerisposed thereon.

The improved device comprises a body portion or receptacle 10 for theliquid to be dispensed, of any required size or of any suitablematerial, and provided with a detachable closure 11, preferably'threadedthereon, the upper surface of the closure being concaved, as at 12, andwith an aperture 13 at the lowest portion of the concaved surface. Depening from the under side of the closure 1 1 is an annular threaded stud14, and engaging y this stud is a spring supporting-sleeve 15.

Slidably disposed upon the sleeve member 15 is a tubular guide member16, and bearing upon the bottom of the receptacle 10 is a cupshapedmember 17, the cup-shaped member and bars 18.

below the apertures,

y held over the same.

guide member connected by spacedv The cup, guide-sleeve, and spacedconnectin-barsare formed from a single section of tu ing, and the cupportion is also provided with spaced apertures 19, through which thechar e of liquid to be emitted at each ac- -tion o the device issupplied to the cup, as

hereinafter explained.

Operating in the cup 17 is a plunger 20, having a` tubular stem 21extending therefrom through supporting member 15 and the aperture 13 inthe closure 11 and terminating in an outwardly-flaring portion or mouth22. Within the mouth portion of the stem 21 a plurality of small curvedducts 23 are formed and connecting y the interior of the tubular stembelow the mouth portion with the interior of the latter to provide anincreased outlet from the stem, as hereinafter explained. The stem 21 isprovided with an intermediate shoulder 24, beneath which apacking-washer 25 bears, the washer also bearing against 'the under faceof the closure member 11. The stem 21 is slightly smaller than the aerture 13 in the closure 11, so that the liqui which may overiiow willdrain back into the receptacle, and to insure this drainage the washer25 is provided with small recesses 26, throughv porting member 15 andexerting its force to maintain the lunger yieldably in elevatedAposition and a ove the inlet-apertures 19.

The improved device herein disclosed is designed more particularly forvthe use of dentists, physicians, and others for holding liquids whichmay be required in small quantities for absorption in sponge, cotton, orsimilar'material for use as an antiseptic or the like, and in using thedevice it is only necessary to press the sponge or cotton upon theHaring mouth 22 of the stem 21 and move the latter downward, whichaction will cause the plunger 20 to pass below the apertures 19 and cutoff the mass of liquid in the receptacle and force the small amountwithin the cup or so much thereof as may be required, upward through thetubular stem 21 and into the absorbent material The iiaring mouth 22 ofthe stem 21 and the curved ducts 23 insure the lateral spraying ordiusion of the liquid and causing it to permeate a relatively large areaof the absorbent, and thus materially increase the utility of thedevice. Any required amount ofthe liquid less than the full contents ofthe cup 17 may be discharged by IOO los

IIO

stopping the downward movement of the stem at any desired point, as willbe obvious.

The device is simple in construction, can be inexpensively manufactured,and of any required size and of any required material.

The parts may be of glass and metal or wholly or partially of rubber orsimilar material, as required.

Having thus described the invention, what is claimed is- 1. In a deviceof the class described, a receptacle having a detachable closure, asupporting member depending Jfrom said closure,

a cup disposed Within said receptacle and provided with intermediateinlet-apertures, supporting means between said cup and supportingmember, a plunger operating in said cup and having a tubular stemextending through said closure, and a spring bearing upon saidsupporting member and operating to maintain said plunger yieldably atone end of its stroke.

2. In a device of the class described, a receptacle having a detachableclosure provided with a threaded annular stud, a threaded supportingmember engaging said stud, a cup disposed Within said receptacle andprovided with intermediate inlet-apertures, supporting means betweensaid cup and supporting member, a plunger operating in said cup andhaving a tubular stem extending through said closure, and a springbearing upon said supporting member and operating to maintain saidplunger yieldably at one end of' its stroke.

3. In a device of the class described, a receptacle having a detachableclosure formed with a concave upper surface, a cup disposed within saidreceptacle and provided with intermediate inlet-apertures, supportingmeans between said cup and closure, a plunger operating in said. cup andprovided with a tubular stem extending through the concaved portion ofsaid closure and with an intermediate shoulder, a washer carried by saidstem and bearing beneath said shoulder and likewise bearing beneath saidclosure, and a sprinr bearing between said supporting member am washerand maintaining said plunger yieldiably at one end of its stroke.

In testimony that I claim the foregoing as my own I have hereto aHixedmy signature in the presence of two witnesses.
